To aehomlit concern.'

Be i lknown that I, KARL HLHANSEN, a subject ofthe 4Emperor 'of Germany; `and `resident of Sewickley in the county of Alleennsylvania,'have in-4 ventedY a. new and useful Improvement in 'Ballers for Cars;and I do hereby -declare ghelly and State of the fOuQWU t0 bea full,.clea r, and exact description tereof.

in the grading for railroad. construction, 'etc.-

The obect of 'my inventionis t9. provide a sprin uier which is sim le in construc-A tion an ,which will relieve t e car not only against a pushin strain," but also a 'pulling strain,- so -that t e wear andtear-.on ',the.4

nnderframe is greatly reducel while at the saine time greater ease in t e starting of the car is obtained. A

In the acct'impanying drawing, Figure 1 is a. plan view of the car underframe, showing my\ invention applied thereto; Fi 2 is :1n-enlarged section on -the line 2.2, iig. 1; is a section on the line4 3 3, Fig. 2.

. In the draiving, the numeral 2- designates" .a suitable car underframeof the round.

bulfer type in the sense that the end portions 3 nre roun .`led, '\vhich` ives greater euse of operation on curves. 'his' underfrume may be made up' of channel members of suit-- i able strength, said frame having thermes- `members 4 :it or nem the `ends and the nuddle cross-member '5.2 The crossmembers 4.

are connected to theframe 2`by the ungles. The buffer cups 7 are prefel'ubly[formed of lute'lnetul bent into U-shupe, the upper` lan( lower plates Send .5), resl'iectvoly, 'of

said Culp inclosing the end. portion 3 of the frame 2 und extending back the propel' dis tance, the top plate 8 of Saul cup resting on the upper l anges of the channel member forming .the front member 4. ,y

The-guides 10` are secured to the front por- 'portion 3 und the chu'nuel v tion 3, nnd'the cross memberA to tlul frame serted in the lides 10 to'reinforce and strengthen the` `uides for the cap member 7, und to .prevent ateral movement of sume, said guides tur ther acting to strengthcnthe niulerfmnw.

My invention relates to `buffers for (cars, and more particularly to cars of the' llghter type for use in industrial work, mines, and

.between the bumpers.

appumm ma my u, me. semi-xo. amis.

A spacer 12 is inserted between the upper and lower plates 8 and V9 of the cap member,

said spacer having an opening 13 formed through it for the passage of the coupling pin 14, said couplin pin being secured in he coupling pin passes throug openingsl formed in the upper and lower plates 8 and'9 of thec'ap member,.and

the cap member is held in place bythe cou- -pling pin so that by the removal ofthe coupling pm thecap plate `mayberemoved for repairs or for the substitution of a new one. "A Spring 16 is interposed .between lthe spacer 12and'the cross-member 4.-, u'nd a. rod

17Y journaled 1n said spacer `and. having the 'head 17* adaptedto seat against a shoulder in the spacer und is 'connected by .the turnbuckle 20 to the rod 21 which in turn is connected to a s acer'of like construction at the Y opposite en of theV frame, Where the,parts u ready reeitedare f luplicated,- so that the buffers at eaehendof 'the nnderframe are connected by 'a continuous drawbur made up of the rods 17 and 21 connected by the turnbnckle.

It may be desirable to form the spacer 12 and' rod 17 as .a singleunit, such as a forging, and I do not desire to limit my invention to theconstruction show n and described.

The coupling` pin 14 has the T-heud 22 which is engaged by the links of the con! pling chin 23. Inf coupling, the link is slipped over the head and turned practically at right. angles so that the link is held be neuth the T4head securely in positiomnnd the eonplinghopcmtion is done w'ithout the i operator having to extend his hands down It 'is Vapparent that other "forms of couplirgpiu head may be employed without.departing from the-princ-iplev ot coupling; for. instance, instead off the T-hcnded piu, n simple hook muy be elnploycd. or the pin. having,lr a hole for the bo'lt of n clevis bitching It is true thutthe pullingr strength is ecceutric'to the center line of lludraw bnr.4 but ol i'ccount. of the width of the buffer und length this forcefis trousfel-red lo lthe draw burs without causing the couplers to twist or bind in any way. und the full strength und service ot' the buffers is obtnined without their having. to be cut out.

It. will be .observed that when one cal' bumps into the other. the buffersfyield under the action ofthe spring to relieve the shock, while' on the other hand, when u pulling force is applied to the buffer the springs also relieve the strain and greater ease 1n starting the car is obtained.

' Furthermore, by my improved form of bufy fer, the buffer projects very little beyond the bility of the hand of the operator getting bef t ween the bumpers in the coupling operatlon.

at I claim isz f y l. he combination with the car underframe, of a sprin actuated buffer engaging said frame, an a 'car couplin pin passing through said buffer inside sai frame.

2. The combination with the car linderframe, of a spring-actuated buffer comprisings VU-sh'aped cap member, a spacer in said cap member, and a coupling pln pass ving through said cap member and said spacer. e

3. The combination with the earY under' frame having cross members intermediate the ends, ca members engaging the end portions of sai Iframe, spacers in said cap members,'springsvinterposed between said spacers ipse-,sse

and said cross members, a connecting Said spacers and coupling pine passing d oivn through cap members and spacer.

4. .The combination with a car underframe having cross-'members intermediate the ends, cap members engaging the ends of the underframe, spacers 1n said cap' members, and

sleeve extensions on said spacers,springs'en` c1 rcling said sleeve extension ,and interposed between saidl spacers and sald cross-members, a rod engaging said sleeve extension,

and a couplinglpm passing through said cap members and t rough said spacers.

5. The combination with a car underframe having cross-members intermediate the ends, cap members engaging the ends of lthe underframe, spacers mlsald cap members, and sleeve extensions on said spacers, springs encircling said sleeve extension and interposed between 'said s acers and said crossmembers, a turnbuckle rod engaging said sleeve extensions, and a coil lingl pin passing .through said capinem rs and through said spacers. l

In testimony whereof, I the said KARL H. HANSEN', have hereunto set my hand.
